Title: Method and device for processing signal and system for displacement detector using the device
Inventor: ISHII SATORU
IPC: G01D5/244
Filed: 1991-04-25
Abstract: PURPOSE:To improve the resolution of a displacement detector or the like by applying arithmetic operation to a sinusoidal wave and a cosine wave signal being reference signals so as to create the sinusoidal wave and the cosine wave signal whose frequency is an integer number of multiple of that of a reference signal. CONSTITUTION:When two signals C1, S1 obtained by the displacement detector are signals expressed as cosomegat, sinomegat respectively, an output S2 of a multiplier 13 is expressed as (1/2)sin2omegat. When an output of an adder 9 and an output of an adder 10 are multiplied by a multiplier 14, an output C2 of the multiplier 14 is expressed as cos2omegat. A signal 2S2 being a multiple of 2 of the output S2 and the output C2 are multiplied, resulting that the output C2 is cos2omegat and the output S2 is sin2omegat. That is, a signal whose frequency is twice is obtained with respect to original two signals as the reference.

Title: Closing circuit of register group
Inventor: CHIBA MASAYASU
IPC: H04M3/26
Filed: 1978-08-04
Abstract: PURPOSE:To enable to have the output of simultaneous group busy monitor and simultaneous group closing, by leading in the closing leads of each register in one group unit. CONSTITUTION:If only No. 1 is busy and others are vacant among the incoming registers IR, at the points A and C of the contact mbo of the closing expansion tree, current flows to IR via the resistor of a high resistance value, the voltage at the points A and C is lower than that at the point X of the busy detection relay BY, it is cut off with the rectifier and no current flows.

Title: Dynamic focus circuit
Inventor: TANAKA HIROSHIGE
IPC: H04N3/26
Filed: 1995-04-20
Abstract: PURPOSE: To prevent a waveform distortion due to power fluctuation of a parabolic voltage of a horizontal period and a vertical period or the like superimposed onto a DC focus voltage of a cathode ray tube. CONSTITUTION: A 1st amplifier circuit is made up of an operational amplifier 1 and its DC operating point is set by a voltage obtained by feeding back its output terminal neutral voltage of a 2nd amplifier circuit (TR1, TR2 or the like) and a 1st power supply B1 via a resistor (at its noninverting input terminal). On the other hand, a 2nd amplifier circuit (cascade connection of the TRs 1, 2) as an output circuit is directly coupled with the 1st amplifier circuit in terms of DC and the power supply is supplied from the 2nd power supply B2. When a neutral voltage Vo of the 2nd amplifier circuit is decreased, the voltage at the noninverting input terminal is decreased and the neutral voltage of the output terminal is decreased by the noninverting input. The reduction acts like increasing the neutral voltage of the output circuit coupled directly.  Thus, fluctuation in the neutral voltage of the output circuit is compensated and a deformed parabolic wave is prevented.

Title: Internal-combustion engine with supercharger
Inventor: TSUKAMOTO HIROAKI
IPC: F02B31/00
Filed: 1982-06-04
Abstract: PURPOSE:To obtain excellent combustion efficiency and torque extending over the whole operating region by forming a throat section deviating the direction of inflow of a mixture flowing into a cylinder through an air-supply port to an air- supply path in a cylinder head. CONSTITUTION:In the internal-combustion engie with the supercharger in which a compressor 5 driven by a turbine 9 using exhaust gas as a power source is disposed into an air-supply pipe 4, the throat section 21 formed by a crescent- shaped projection 22 integrally formed to the cylinder head 2 is formed to the air-supply path in the cylinder head 2 communicated with the air-supply port 3. Accordingly, said projection 22 can inhibit the blow-over of exhaust gas generated when suction and exhaust valves 13, 14 overlap because the turbine 9 functions as an exhaust resistor on operation at low speed. Combustion efficiency is improved because the throat section 21 deviates the direction of inflow of the mixture flowing into a combustion chamber 12 and generates a swirl and a turbulence in the combustion chamber 12.

Title: Safety device of welding robot
Inventor: KITSUI AKIO
IPC: B25J17/02
Filed: 1980-07-15
Abstract: PURPOSE:To prevent damaging of a welding torch or its holding mechanism by providing means of retreating a wrist mechanism part consiting of a driving device, a welding torch, etc. when abnormal strong force is exerted upon said part to said mechanism part. CONSTITUTION:Stoppers 6, 6' are provided in one piece to a stationary plate 7, and a stationary side stopper 5 is projected to an oscillating motor 3. When the entire part of a wrist mechanism part moves in an arrow A direction, and a torch 12 strikes against an obstacle 16, breaking of the stoppers 6, 6' does not occur because a torch mounting base 11 and stationary plates 7, 7' are mounted separately to an output shaft 10. Even if the oscillation side stopper 6 or 6' abuts on the stationary side stopper 5, the base 11 is moutned to the shaft 10 via a retaining member 17 and stopper rings 18, 18' by the tightening force of bolts 19 for stopper rings 19 and therefore it slips between the member 17, and the rings 18, 18', and does not break the stoppers 6, 6', 5. In this way, the internal breakdown of the motor 3 is prevented.

Abstract: PURPOSE: To make it possible to carry out the effective heating operation, by providing a frosting condition detection circuit, the first timer circuit, a counter, the second timer circuit etc., and performing an optimum defrosting operation in accordance with frosting conditions on an outdoor heat exchanger.  
     CONSTITUTION: When a defrosting start signal has been issued from a frosting condition detection circuit 40, a defrosting signal is issued from the first timer circuit 80 for about 5min, and at the same time a defrosting signal is issued from a second timer circuit 81 for about 10min. Thus based on the action of the second timer circuit 81 a defrosting operation will be carried for about 10min. In this case, the counted contents in a quaternary counter 82 will be cleared by the defrosting signal issued from the second timer circuit 81. Thus every time when the defrosting operation is carried out for about 5min three times based on the action of the first timer circuit 80, the defrosting operation based on the action of the second timer circuit 81 is carried out for about 10min.

Abstract: PURPOSE:To realize the speaker equipment for the AV system with excellent sound image localization by specifying an outer size of a diaphragm of the speaker equipment within a reproduction range of a frequency giving a large effect on a sense of sound image localization. CONSTITUTION:Plural low sound frequency speakers are arranged at a symmetrical position with respect to a horizontal and vertical line around a reference point, the outer size of a diaphragm in the horizontal direction is selected to be 0.32mm or over and the outer size of the diaphragm in the vertical direction is selected to be 0.61mm or over. Four woofers 22a, 22b, 22c, 22d are fitted by selecting an interval dH between the woofers 22a, 22c and the woofers 22b, 22d in the horizontal direction to be smaller than the vertical interval, that is, an interval dV between the woofers 22a, 22b and the woofers 22c, 22d in the vertical direction. Then a tweeter in the middle such as a horn speaker 23 is fitted to the center of a cabinet 21. A constant directivity horn speaker whose directive angle is 80 deg. in the horizontal direction and 40 deg. in the vertical direction is adopted for the horn speaker 23. Thus, the speaker equipment for the AV system giving no effect onto a sense of sound image localization is obtained even in a comparatively narrow space.
